proportion of visitors on diving holidays, and many others
making day trips to reefs. Most tourists remain on the
granitic islands, but there are now also some exclusive
developments on the outer islands, while boat-based
holidays take tourists to most areas.
Land reclamation has built upon, and destroyed, a
large area of the fringing reefs of east Mahe, which
were once the best developed fringing reefs in the country.
This work has also had impacts on the adjacent reefs
through heavy sedimentation. Elsewhere terrestrial sources
of sewage pollution, sediments, and solid waste are
problematic, while the increases in tourism are bringing
these problems to new areas.
There is a clear awareness of environmental issues
at the governmental level and efforts are being made to
improve sewage treatment in some areas. A number of
marine protected areas have been established and active
management is underway. The remote island of Aldabra has
long been recognized for its unique flora and fauna and is
well protected, with a research station and permanent staff.

The bank of shallow water around Providence and Cerf Islands has the appearance of a true platform reef, although
recent studies have shown that there is very little living coral on its seaward margins, while the surface is dominated by
seagrass ISTS033-76-43, 19891.
